Problem Description
If you come across embedding YouTube videos to your website, you might know this problem. When some elements in your page
have a higher z-index to float on other elements, the YouTube embedded video ignores their z-index and hides them under it.
Tip
A simple way to solve this is to add the wmode=transparent property to the source URL of the video:
<iframe width="752" height="425" src="http://www.youtube.com/embed/O2R-ixfQtwE?wmode=transparent&rel=0&modestbranding=1"
frameborder="0" allowfullscreen=""></iframe>
